Dear EIC team members,



At this stage, the Conceptual Design Report (CDR) should be used as the baseline for the EIC technical design in all aspects. As the project evolves, major technical improvements/changes, after a designated procedure, shall re-establish the baseline locally or affecting a broad range.



After formal reviews and collection of comments from the Technical Change Control Board, I have approved the following change to be implemented into the EIC technical design baseline:



Change the primary pumping configuration of the ESR to NEG coating

(original: The primary pumping configuration of the ESR was using NEG strips )
